For an app to train your memory skills, I am trying to create a layout like this

Line 1: number1 number2

Line 2: countdown timer

Line 3: seconds left to remember

bottom of screen: done button

Visual mockup can be found here:

I have been struggling with this layout for the past six hours, have searched Google and this forum extensively, yet am at the end of it. For the life of me, the two TextViews that hold the numbers to remember get shown below each other instead of side by side.

I thought a simple change of the LinearLayout's orientation from android:orientation="vertical" to android:orientation="horizontal" would help yet the result on screen was totally messed up. What am I doing wrong?
